54305019 ÷ 507 
Our goal is to divide 54305019 by 507.

Going ahead to step 1:
If we divide 5 by 507, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 507

Moving on to step 2:
507 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 507

Advancing to step 3:
The number 507 fits into 543 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 507 from 543 leaves us with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 507

Step 4:
The number 507 fits into 360 0 times, leaving a remainder of 360.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 360 leaves us with 360.
Fetch the next digit (5) from the dividend, attach it to 360 and continue: 3605 / 507

Step 5:
When dividing 3605 by 507, we get 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 3549 away from 3605, we end up with 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 507

Advancing to step 6:
The number 507 fits into 560 1 times, leaving a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1071.0
If we take 507 away from 560, we end up with 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 507

Let's proceed to step 7:
The number 507 fits into 531 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 10711.0
Subtracting 507 from 531 leaves us with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 507

Moving on to step 8:
If we divide 249 by 507, we get 0 and a remainder of 249.
Record the quotient 0 as the next digit in the result. 
Result so far: 107110.0
If we subtract 0 from 249, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 9:
When dividing 2490 by 507, we get 4 with a remainder of 462.
Put 4 as the next digit of the answer. 
Result so far: 107110.4
The remainder is 462 after subtracting 2028 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 10:
507 goes into 4620 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 107110.49
Subtracting 4563 from 4620 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
When dividing 570 by 507, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 107110.491
If we take 507 away from 570, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
630 divided by 507 is 1 with a remainder of 123.
Put 1 as the next digit of the answer. 
Result so far: 107110.4911
Subtracting 507 from 630 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The final result is 107110.4911 with a remainder of 0.00123.
